Description

I built a multi-agent supervisor following the link agent_supervisor. I found that after setting the step_timeout for the agents, an error occurs. However, when I remove that line of code, there are no errors. Why is this happening?

I found that after setting the step_timeout for the agents, an error occurs. However, when I remove that line of code, there are no errors. Why is this happening? ### System Info System Information ------------------ > OS: Linux > OS Version: #228-Ubuntu SMP Fri Feb 7 19:41:33 UTC 2025 > Python Version: 3.9.1 (default, Feb 9 2021, 07:42:03) [GCC 8.3.0] Package Information ------------------- > langchain_core: 0.3.59 > langchain: 0.3.25 > langchain_community: 0.3.24 > langsmith: 0.3.37 > langchain_anthropic: 0.3.12 > langchain_experimental: 0.3.4 > langchain_nvidia: Installed.
